If the jointer is to be hard-wired to a panel, make

sure a disconnect is available for the operator.

During hard-wiring of the machine, make sure

the fuses have been removed or the breakers

have been tripped in the circuit to which the

jointer will be connected. Place a warning

placard on the fuse holder or circuit breaker to

prevent it being turned on while the machine is

being wired.

Grounding Instructions

This machine must be grounded. In the event of

a malfunction or breakdown, grounding provides

a path of least resistance for electric current to

reduce the risk of electric shock.

Improper connection of the equipment-

grounding conductor can result in a risk of

electric shock. The conductor with insulation

having an outer surface that is green with or

without yellow stripes, is the equipment-

grounding conductor. If repair or replacement of

the electric cord or plug is necessary, do not

connect the equipment-grounding conductor to a

live terminal.

Check with a qualified electrician or service

personnel if the grounding instructions are not

completely understood, or if in doubt as to

whether the tool is properly grounded. Repair or

replace a damaged or worn cord immediately.

IMPORTANT: Make sure the electrical

characteristics listed on the motor nameplate

match those of the power source, and make

sure the circuit on which the jointer will be used

is properly fused and that the wire size is

correct.

Converting from 230 Volt to 460 Volt

(Three Phase Only)

Refer to Figure 14.

Consult the wiring diagram inside the starter box

cover. A similar diagram is also included at the

back of this manual. The Jointer must comply

with all local and national codes after being

wired.

1. Remove the starter box cover and adjust the

dial on the overload relay as close as

possible to the amperage of the motor at

460V, as listed on the jointer’s motor plate.

2. Move the fuse from the 230V slot to the

460V slot.

3. Re-connect the incoming leads to the motor

in accordance with 460 volt operation, as

shown in the wiring diagram.

4. If using a plug, install a proper UL/CSA

listed plug suitable for 460 volt operation.
